AFAIK, there is no formula.
For trading up, you have to make an offer that makes the other party look like they got themselves a good deal without screwing yourself over. Like ๐น๐น might give away our 1st and 3rd for their 1st. Then he might trade other picks for more picks with someone else as ๐น๐น likes lots of draft picks.
